STRIP-REELING APPARATUS COMPRISING A BELT COILER Filed Feb. 15, 1965 2 Sheets-Sheet 2 United States Patent 3,321,949 STRlP-REELING APPARATUS COMPRISING A BELT COILER Hans Werner Marx, Dusseldorf, Germany, assignor to Schloemann Alttiengesellschaft, Dusseldorf, Germany, a German company Filed Feb. 15, 1965, Ser. No. 432,755 Claims priority, application Germany, Feb. 25, 1964, Sch 34,704 4 Claims. (Cl. 72148) This invention relates to a belt coiler, which is arranged between two strip reels located one behind the other, which are to be filled alternately. In a known manner the problem of a belt coiler consists in bringing the leading end of a strip accruing from a rolling mill into operative connection with a reel drum, and holding it thereon until so many turns of strip are wound upon the reel drum that a slip free reeling of the strip is ensured without any additional application of pressure. In order that the looping angle or angle of grip of the belt of the strip-coiler, for the attainment of a reliable introduction of the leading end of the strip into the first turn of the strip may be as large as possible, the belt is passed around a hinged bridge provided with rollers, and this hinged bridge, after the belt coiler has travelled towards the reel drum, is rocked upwards. Furthermore, for the attainment of a slip-free pressing of the strip against the reel drum, the belt must additionally be brought into operative connection with a belt-tightener.

If, for example, the strip accruing from a Konti mill train is being reeled, it is necessary, for the maintenance of continuous working, to provide at least two strip reels, in order that as soon as one reel is filled, reeling may be immediately continued upon the other reel.

Hitherto it has been necessary to provide a separate belt coiler for each reel. The object of this invention consists in employing, for both strip reels, the same belt coiler, which is arranged between two alternately filled strip reels located one behind the other.

According to the invention, this is attained in a simple manner by equipping the belt coiler with two hinged bridges arranged opposite to one another, which cooperate with a common belt.

In a further development of the invention, the hinged bridge that is not for the time being needed for coiling a reel drum becomes operative as a belt-tightener, so that separate belt-tighteners may be omitted.

In order to ensure looping angles of the same size on the two reels, with the same position of the strip-inserting aperture, the amplitude of rocking of the rear hinged bridge is made correspondingly greater than that of the front bridge. Owing to this arrangement it is possible, for one thing, in a known manner, to move the belt coiler in a direction opposite to the direction of arrival of the strip, as well as in the direction of arrival of the strip. This yields, as an additional advantage, identical strip-supplying arrangements for the two reels.

One constructional example of the invention is illustrated in the accompanying drawings, in which:

FIGURES 1 and 2 show the belt coiler diagrammatically in the two diiferent operative positions.

In the position of the belt coiler 1 in FIGURE 1, a strip 2 coming from a rolling mill runs in between driving rollers 3 and a reaction roller 4, and over guiding rollers 5, to a reel drum 6, in a direction opposite to the direction of travel of the belt coiler. In the starting position shown, a hinged bridge 7, provided with guiding rollers and 11 for the belt 12 of the coiler 1, has been rocked downwards by means of a power cylinder 3,321,949 Patented May 30, 1967 9, which is rockably supported about a pivotal axis 8. By rocking the hinged bridge 7 upwards about its pivotal axis 13, by means of the power cylinder 9, the portion 12 (represented by dotted lines) of the belt 12 is Wrapped partly round the reel drum 6, so that the drum is almost surrounded by the belt. Thereupon, by actuating a second power cylinder 15, which is rockable about a pivotal axis 14, a second hinged bridge 17, provided with guiding rollers 18 and 19, is rocked outwards (as shown in dotted lines) to the position 19 about pivotal axis 16, and thus keeps the belt taut. As soon as a few turns of the strip 2 have been wound upon the reel drum, the belt coiler, by rocking the hinged bridge 7 down again, is moved away from the reel drum 6. During this movement the hinged bridge 17 rocks inwards, and thus delivers the appropriate length of belt for the rocking of the bridge 7.

In the operative position of the belt coiler 1 of FIG- URE 2, the strip 2 runs in, deflected by the guide rollers 20 and 21 and by the reaction roller 22 and delivered by the driving rollers 23, in the starting direction of the belt coiler 1. The amplitude of rocking of the hinged bridge 17 is made greater than that of the hinged bridge 7, in order that in its operative position (represented by dotted lines) as large a wrapping angle as possible of the belt 12 round the reel drum 24 may be attainable.

By ill and 19 are denoted, in each case, the guiding rollers it) and 19 in the deflected position of the associated hinged bridge 7 and 17 respectively. 25 and 26 denote further guiding rollers for the belt. The belt coiler is transportable on wheels 27.

I claim:

1. Strip-reeling apparatus, comprising: two stationary strip reels, a reel drum rotatably mounted on each of the said strip reels, means for feeding a strip coming from a common source to the two strip reels alternately, a belt wrapper capable of traveling to and fro between the two strip reels, guiding rollers rotatably mounted on the belt wrapper, and a common endless belt passing around the said guiding rollers.

2. Strip-reeling apparatus as claimed in claim 1, further comprising: two hinged bridges rockably mounted on the belt wrapper, one at each end, a guiding roller rotatably mounted at the free end of each of the hinged bridges, the said endless belt passing around these two guiding rollers as well as around those mounted directly upon the belt wrapper, and means for rocking the hinged bridges.

3. Strip-reeling apparatus as claimed in claim 2, the means for rocking the hinged bridges being adapted to rock them alternately into such positions that one of them wraps the belt, and therefore the strip, around one of the reel dnims, while the other hinged bridge at the same time tensions the belt.

4. Strip-reeling apparatus as claimed in claim 3, the means for rocking the hinged bridges including in each case a cylinder-and-piston power unit.
